+# Integrations
+
+The dd can be integrated with other systems using their APIs.
+
+## Autentication
+
+All requests must be authenticated with a [Json Web Token (JWT)][jwt],
+and must be signed with the `API_SECRET` (defined in `dd.conf`).
+
+This authentication is done with the `Authentication` http header.

+```sh
+> curl -H "Authorization: bearer ${jwt}" https://admin.DOMAIN/ddapi/roles
+[
+  {
+    "keycloak_id": "9325ad99-7e04-4c31-9768-5512e1564160",
+    "id": "admin",
+    "name": "admin",
+    "description": "${role_admin}"
+  },
+  {
+    "keycloak_id": "c6c8a73e-51fc-4716-831d-1dfc0e0b62b0",
+    "id": "manager",
+    "name": "manager",
+    "description": "Realm managers"
+  },
+  {
+    "keycloak_id": "24d7977e-da83-4591-8e13-0fac3126afa1",
+    "id": "student",
+    "name": "student",
+    "description": "Realm students"
+  },
+  {
+    "keycloak_id": "d6699c41-13d5-4623-bdca-e5f2775474ed",
+    "id": "teacher",
+    "name": "teacher",
+    "description": "Realm teachers"
+  }
+]
+```
+
+Where <code>JWT</code> can be generated, e.g. using <code>python-jose</code>:
+
+```python
+import os
+from jose import jws
+t = jws.sign({}, os.environ["API_SECRET"], algorithm="HS256")
+print(t)
+```
+
+Other programming languages have similar ways of generating tokens.
